Technical description

In the Linux kernel, the following vulnerability has been resolved:

gpu: host1x: Fix memory leak of device names

The device names allocated by dev_set_name() need be freed

before module unloading, but they can not be freed because

the kobject's refcount which was set in device_initialize()

has not be decreased to 0.

As comment of device_add() says, if it fails, use only

put_device() drop the refcount, then the name will be

freed in kobejct_cleanup().

device_del() and put_device() can be replaced with

device_unregister(), so call it to unregister the added

successfully devices, and just call put_device() to the

not added device.

Add a release() function to device to avoid null release()

function WARNING in device_release(), it's empty, because

the context devices are freed together in

host1x_memory_context_list_free().

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
